To all whom t may concern.'

Be it known that l, HERBERT W. SYMoNDs, a citizen of the United States,and a resident i of St. Louis, Missouri, have invented certain new anduseful Improvements in Hot-Air Registers, of which the following is aspeci iication.

My invention relates to a hot-air register, of what is known in the artas the wall type, and has for its object to provide a `register havingthree principal elements,

namely, a frame, a single valve horizontally and detachably pivoted insaid frame, and a grille or grating horizontally and detachably pivotedin the frame to actuate the valve; combining therewith means forlimiting the movement of the grille and valve, to the end of preventingthe complete throttling of the hot air flue by the valve; This latterfeature is of value and utility whereverV a single hot-air flue isintended to supply heated air to two or more registers, and is intendedto prevent the entire diversion of the ascending heated air by either ofthe registers which are arranged in series, except the last register inthe series'. Furthermore, the valve-limiting mechanism is so arranged asnot only to adj ustably limit the movement of the valve, but topreventthe adjustment from being altered or tampered with after the register isseated in place.

In the drawings Figure 1 is a front elevation of a register involving myinvention, seated in place for use.

Fig. 2 is a transverse horizontal view in section of the same, taken onthe line 2 2 of Fig. 1.

F ig. 3 is a vertical sectional view of the same, and the hot air supplyflue.

Fig. 4 is a fragmental rear elevation of a register embodied in myinvention.

Fig. 5 is a transverse sectional view taken on the line 2 2 of Fig. 1,and illustrating the frictional contacting points at which the grille isheld in place within the frame, and the manner in which the grille issprung into place, in the course of assembling.

Fig. 6 is a detail view taken on the line 6 6 of Fig. 5, showing theleft hand trunnion of the frame, and the depending camface of the grilleadapted to contactwith said trunnion, in the position which it occupiesjust before it is sprung into place.

Fig. 7 is a like view, on the line 6 6 of Fig. 5, showing the left handbearing of the grille in contact with and seated in place upon the lefthand trunnion of the frame.

Fig. 8 is a transverse sectional view taken on the line 8 8 of Fig. 5;'showing the seating of the right-hand bearing of the 1 grille upon therighthand trunnion of the frame.

Fig. 9 is a vertical sectional view of a fragment of a building, showingthe seating of two registers upon a vertical hot-air iiue; the lowerregister being unprovided with means for regulating and limiting thethrow or movement of the valve, with `the consequence of a completethrottling of the Hue bythe lirst register, thus depriving the occupantsof the upper right-hand room of heat. rFhe upper register isillustratedas containing the valve whose movement is limited inaccordance with my present invention, with the result of preventingtotal or complete throttling of the flue by its use.

The frame 10 is provided with the valve trunnions 11, located, as shown,and projecting inwardly from the inner vertical edges of the frame nearits top, for the re-V ceptionof the ends of the horizontal channel l2with which the valve 13 is provided along its upper horizontal edge. Thevalve 13 is hooked into place as illustrated in Figs. 1, 3,4, and 9;thev depending fret-work 14 with which the frame 10 is provided alongits upper and inner horizontal edge serving to exert frictional contactat points along the front and convex surface of the channel 12.

A link-bar 15 is pivotally mounted on the valve 13, its front extremityhaving the eye 16 which engages with the pintle 17 with which the grille18 is provided.

The frame 10 at the center of its lower inner edge is provided with theupwardly projecting friction-post 19, which has frictional contact withthe inner face of the grille 18 in the manner illustrated in Figs. 1, 2and 5, its top projecting slightly forward as shown in Fig. 5. The frameis also provided with a right-hand trunnion 20 which engages with theright-hand bearing or channel 21, on the position, Which latter positionis shown in Fig. 7 l

As I have indicated above, the use of a single valve register, such asIhave indicated as A in Fig. 9, enables its user, under ordinaryconditions of installation and iiue construction, to completelythrottle, and divert all of the ascending heated air from the iiue B, asillustrated in Fig. 9. To overcome this difliculty, which is productiveof trouble as between the tenants of upper and lower Iioors, whoseregisters are fed by the same flue, I have provided the grille 18 with apin 25, whose outer end is fixed near the lower edge of the grille 18,and whose inner end is curved as shown in Fig. 3, passes through n anorifice in the post 19, and its extremity is screw threaded and providedwith a nut 26 and lock-nut 27, which nuts are adjusted and locked beforetheregister is seated in place, and when so seated, cannot be reached ortampered with by the tenant or user.

The frame 10 is channeled as indicated by the numeral 28 so as to beseated in the flue frame 29 with which the flue B is provided. `When soseated, the movement of the valve 13 is limited by the mechanism justdescribed, so that its inward throw will not carry the valve 13 to theback wall of the iiue B, the illustration of such register, and thelimitation of the movement of its valve beingindicated by the upperregister, indicated as C, in Fig. 9.

By reason of the construction shown, the valve 13 is readily removablefrom the frame 10, and its connecting'link 15 is readily detachable fromthe pintle 17 So, also, the grille 18 is readily removable from theframe 10, the nut 26 and lock-nut 27 being first removed from the pin25.

As shown in Figs. 3 and 4, the valve 13 is provided with a perforation30, to accommodate the rearwardly projecting end of the pin 25 and thenuts 26 and 27.

Having thus described my invention, what I claim as new, and desire tohave secured to me by the grant of Letters Patent, is-

1. In a hot-air register, a frame provided near the lower ends of itsinner vertical edges with inwardly projected trunnions and at the centerof its lower horizontal inner edge with an upwardly projecting frictionpost, a grille removably and pivotally mounted in said frame byfrictional Contact with said trunnions and said friction post, and a,single valve horizontally pivoted in said frame and actuated by saidgrille.

2. In a hot-air register, a frame, a single valve horizontally pivotedin said frame, a grille horizontally pivoted in said frame to actuatesaid valve, and means for limiting the movement of said valve havingadjustable mechanism so located as to be inaccessible when the registeris seated in place.

In testimony whereof, I have signed my name to this specification, inpresence of two subscribing witnesses.
